None of the options changed (to my knowledge) between the patches up to

Changes came with 2.0 when the cache was ripped out of the proxy.

Not really. mod_proxy has been maintained and bugfixes applied by me and
others since 1.3.9 (or thereabouts).

1.3.12 worked great for me.

Try it out on a test system and see if it works, or implement a backout
plan. I'd do this regardless of mod_proxy's status as working or not.

When I created the patch for 1.3.12 I took special care to ensure that
the proxy patch and the SSL patch did not clash with each other (apply
the SSL patch first, then the proxy patch).

I'm not sure if the same is still true for the 1.3.19 patch, been a
while since I built 1.3 Apache.

Apply the proxy patch to the SSL patched Apache, not the other way
around. At worst there should be a small conflict in proxy_http.c (if
memory serves), which should be fixed without too much hassle.
